MACHINE FOR DYEING FUR-SKINS.

To all whom it may concern: 7

Be it known that I, MALCOLM DIOKERSON, a citizen of the United States,residing in Belleville, in the State of New Jersey, have inventedcertain new and useful Improveskins has been hitherto a hand operation,the

dye being applied to the fur and distributed uniformly by a brush'in thehands of the operator, the fur skin to be dyed being. laid upon asuitable table and removed therefrom and hung upon a suitable frame inorder that it may dry without pressure upon the 'fur and without contactof the flesh side of one skin with the wet fur of another skin. Thishand operation is necessarily slow and expensive. Efforts have been madeto produce a'machine capableof performing the operation rapidly, buthitherto such efforts have not resulted in a thoroughly satisfactorymachine, mainly because it has sought to handle the fur skin in the samemanner that a skin without fur might be handled satisfactorily, thenecessity of avoiding application of the dye to ,thelflesh side of theskin and of avoiding the matting of the fur by pressure thereon whilethe fur is still wet, not being fully' recognized or provided for. Bythe present invention it has been sought, while making use of such mainelements as have been used heretofore,

so to improve the construction as to meet in a satisfactory manner thepeculiar necessities of the satisfactory treatment of fur skins.

It has been the further object of the invention to produce a'machinewhich has coinparatively few parts, all of which are ao cessible readilyfor cleaning, renewal and repair, is comparatively inexpensive,--'and iscapable of performing the intended operation rapidly and efficiently.The invention will be fully described hereinafter with reference to theaccompanying drawings in which it is illustrated and in which Figure 1is a topview of one form of a machine which embodies the invention. 7

The working parts of the machine are supported upon a suitable framewhich comprises a lower frame a provided with level-- ing screws a, adrip pan a which also forms a part of the frame, being secured by bolts(1 to the lower frame members a, and upper frame members or cheek piecesa secured to I the lower frame members by bolts a The upper framemembers or cheek pieces a are provided with bearings a in which ismounted askin carrier, so that it is removable readily when necessary.The skin carrier might be a rotary drum, as shown at b in Fig. 10, or,as shown particularly in Figs. 5, 7 and 8, it comprises a frame I)having trunnions b to be received in the bearings a", a curvedshoe 6covered by a non-friction and non-corrosive lining 6 such as a sheet ofcelluloid, bearings at'b and b the latter being adjustable, as by, ascrew 6 rolls 6 and 12 mounted in the bearings b and b 'respectively,and an endless belt 72 of rubber or other suitable material, whichencircles the rolls 6 and b and the shoe 6 and is caused to travel in acounter clock-wise direction, a driving pinion 6 being fixed on the endof one of the rolls, as

the roll 6 and engaged by a driving chain as hereinafter described. Theshoe 6 is suitably curved, as shown in Figs. 5 and 8, and the tension ofthe belt can be regulated by adjusting the bearings b of the roll 6 JThe skin carrier, whether a drum or a belt, is wetted more or less withthe dye, as will be explained, and it is very necessary to remove fromthe surface of the belt or trough and is applied to the fur.

For this'purpose a squeeze roll 0 is mount- ,ed in movablebearing boxes 0, pressed toward the skin carrier b s orin s c and suported'by brackets c suitably mounted in is a dye trough (Z which may besuitably supported betweenthe upper side members a by spring-pressedrolls (Z, carried by lugs (Z2, and normally engaging holes formed in theframe members a. The dye is supplied to the trough through a suitablepipe (Z at the middle of the trough, and the excess of the dye, nottaken up by the brush hereinafter described, flows out from the troughat its ends, as indicated at (Z falling thence upon the pan a to becollected and re turned, if desired, to the trough throu, ;h-the pipedAs the brush referred to rotates there might bea tendency of the dyeliquor to eddy in the trough and pile up more or less near the ends. ,Toovercome such tendency, the trough is provided, near each end, betweenthe outlet andthe inlet,'with a partition (i which is lower than the endof the trough, as shown in ig. 5, so that the dye liquor at the end ofthe space occupied by the brush flows over the partition and escapesthrough the opening rltwithout pil= ing up in the trough at the end ofthe brush.

The fur skin is held with the flesh side againstthe endless belt b ashereinafter described, and moves with it under the shoe '5 with the furdownward. A dye-applying, cylindrical brushe is supported in suitablebearings so as to be rotated at a moderate speed and so as to bepartially submerged in the dye liquor in the trough CZ, the direction ofthe rotation being clock-wise so that the direction of movement of thesurface of the brush, where it contacts with the fur, shall be the sameas that ofthe fur. By this means the'dye is taken from the 7 Any eX-cess of dye thrown oil by the brush is thrown forward, to fall into thepan a .or to be taken up by the first rubbing-in brush 7 which islikewise mounted in suitable bear-v lugs and 1s rotated also in aclock-w1se direction, but at a much higher speed than the brush 0. Asecond rubbing-in brush 9 is also mounted in the frame to rotate in aclock-wise direction at a relatively high 7 draft.

speed. It will be understood that the bearings of the brushes 6, f andgare adjusted as indicated at e f and 9 in Fig. 2, so that the brushesmay. bev moved toward or away from the skin carrier The effect of thetwo rubbing-in brushes-is to spread the essary action of the rapidlyrotating brushes,

f andg,'while at the same time they must be held by. such means that thedye liquor shall be applied to all parts oflthe fur. To effect thisresult endless cords h are mounted on grooved guide rollers h", if, hand h and bear against the underside 'of the skin carrier, as clearlyindicated in Fig. 5. One or more of the grooved rollers are driven, ashereinafter described, so that the lineal speed of'the cords shall besubstantially the same i as that of the belt 5 and so that thecontacting portions of'the cords and the belt vor skins shall move inthe same direction; In order to avoid the necessity of providingadjustable means for maintaining the tension of the cords, the rollhreceives a slightly higher speed ofrotation than the rolls h and 7 It,so that the workingportion of each cord is maintained under suitabletension by the The slippage is 'inconsiderablel It is highly'importantthat the wet fur, as 'it comes from the last rubbingd'n brush g,'shallnot be subjected to pressure, so that'the wet fur shall not be matteddown. To accom- V plish this result the grooved roll ifi'is placed at aconsiderable distance beyond the roll 1b,

thereby providing a table of cords on which each skin, as it leavesthelast'brush, shall rest lightly and at the same time move fordryingwithout having any other skin resting upon it; The cords are smallln sze and do not in pract ce prevent a'unlform d1str1-- bution of the dyeonthe fur;
